When ever I was bad as a child my mother would remind me that in the Yukon, Eskimos eat their children.

(okay, she was way politically incorrect) but I do remind my cats when they won't let me sleep in that they eat cat in many countries.

In the spirit of true confessions, I also used to tell my son I was going to sell him to gypsies. Apparently it hurt his feelings. (His younger brother plays the accordian now, hmmmmm).
